As an Olympic lifter, Hilligenn was the first South African to Clean and Jerk double body weight.
His lifts in 1946 were Press: 245 pounds, Snatch: 255 Pounds and Clean & Jerk: 321 pounds. In the early 1950’s, and weighing just 173 pounds, Hilligen unofficially equaled the world record in the Clean & Jerk with a lift of 375 pounds. He actually finished second in the 1951 National championships to Norbert Schemansky.
Hilligen eventually Clean & Jerked 405 at a slightly heavier body weight, which was an unofficial world record at the time. It was voted as one of the greatest “lifts” of all time. Hilligenn also “cleaned” a pair of 142-pound dumbbells (but did not press them) at Ed Yarick’s Gym in Oakland, California in the 50’s.
Interestingly, Roy Hilligenn was also a life-long vegetarian and claimed to have never eaten meat ever.
